if i get an apexi s-afc fuel controller, and a s-acv boost controller do i still need to get the ecu chipped?

i thought the ecu had to be chipped to change the fuel mapping and limits, but would the fuel controller override this?

oh and does anyone know of a decent air/fuel ratio meter? will the apexi show this? i dunno.

and while i'm at it why doesnt nayone appear to do a charge cooler for the 300? as opposed to intercoolers

Scoops, alot really depends on how far you want to mod, the AFC will adjust your fueling for you no probs, how ever one of a chips functions is to alter fueling but in line with other parameters, which in turn bring increased horse power, fitting the Apexi's after a chip will fine tune the chips settings ( which are often just preset for a range of mods) and enable you to gain a little more power but more importantly ensuring all settings are correct and safe for YOUR particular mods, so in short NO you don't have too, but you'll get more if you do chip as well. I use a Lumention small black box, £70 from Demon tweeks, it has 9 coloured lights that tell you the status of fuel mixture, nice and compact and looks well at nite, don't forget the ECU is a closed loop application, so take no notice of readings on it until after 2,750 revs.

Dunno if the AFC has this function.

Lastly charge coolers, could take some working on a Zed i would imagine, it's just another rad in principal which needs cooling and should the water jacket ever burst, can fill the engines internals full of water, hope some of this helps.

cheers

smithy :cool:

cheers matey that clears things up a bit.
